Question

evaluate the expression when y=2.
y² -5y + 2

Explanation:

Step1: Substitute \( y = 2 \) into the expression

Substitute \( y = 2 \) into \( y^2 - 5y + 2 \), we get \( 2^2 - 5\times2 + 2 \).

Step2: Calculate each term

Calculate \( 2^2 = 4 \), \( 5\times2 = 10 \). Then the expression becomes \( 4 - 10 + 2 \).

Step3: Perform the arithmetic operations

First, \( 4 - 10 = -6 \), then \( -6 + 2 = -4 \).

Answer:

\(-4\)
